MACHINE'FOR SUMMING UP- NUMERAL DATA.

Application filed April 7, 1920. Serial No. 372,005.

To all whom 'z'fmay concern:

Be it known that I, KARL EMIL LEONARD Lmns'rnAND, a subject of the King of tain new and useful Sweden, residing at Volmar-Yxkullsgatan 9, Stockholm, Sweden," have invented cerimprovements 1 in machines for summing up numeral. data represented by slots or the like provided in'the Letters Patent No. 1,261,413 or No.

1,334,957. The said slots may represent certain numeral data for instance insurance amounts, in which case a plurality of slots are used for indicating the amount by units, tens, hundreds, etc. This invention relates to a machine, by means of which the said numeral data may be summedup. The said machine is so arranged, that the cards of a collection are successively caused to pass through a calculating machine, during which operation pins, swingable arms provided' witlr'rollers, or the like enter the slots respectively and cause a calculating device to operate during a period, corre s onding to the hangth of the slot, so that the said device is shifted in accordance with the numeral, represented by the slot. sides, the said machine is so arranged, that it counts the number of cardshaving passed through the machine.

In the accompanying drawings Figs. 1 and 2 show in a section 'and an end view respectively a device adapted to feed the shows a card, which is arranged in accord;

ance with the Letters Patent No. 1,334,957 and the numeral data of which may be summed up by means of the machine shown in Fig. 6. Fi 8 and 9" show in side views details in di erent positions. Fig. 10 1s an edge view of the parts shown in Fig. 9.

1, Figs. 1 and 2, is a casing, in which a set of cards is located, the numeral data of which are to be summed up. The cards are designated. by 2. The said set is forced toward the open side of the casing by a piston 4 acted upon by a spring 3. At the said side of the casing a plate 5 is slidably mounted, against which the set of cards is forced and which is moved upward and downward by a crank 6 and pitman 7 The said plate 5 hasa shoulder 8, which is arranged to engage the foremost card of the set and push the same into the space between two rolls 9, 10, which are rotated by any suitable means. The roll 10 is provided at its ends with pins 11, which engage holes 12 provided in each of the cards 2, as shown in Fig. 5, so that the roll 10 will feed the cards positively. The cards 2 are supported by the bottom-of the casing 1. At the plate 5 a slot is provided in the said bottom, through which the cards may pass one by one. The foremost card, located at the slot, is supported by a catch 13, pivoted at 14 and held in operative position by a spring 15. As the card is pushed downward by the shoulder 8 of the plate 5, the catch 13 yields and permits the card to pass, whereupon the catch is forced upwards and supports the next card advanced by the piston 4. Consequently, the cards 2 are moved in their proper'turns downward to the rolls 9, 10, which forward the same to the calculating machine, Figs. 3 and 4. At the said machine a second pair of feed rolls 16, 17 may be provided, arranged in the same manner as the rolls 9, 10'.

The calculating machine shown in Figs. 3 and 4 has a number of disks 19, which are loosely mounted on a shaft 18 and caused to rotate with the said shaft by means of a tongue engaging notches in the said disks. Each of the disks 19 is preferably mounted between a plate 22 and a spring 23 extending u ward from a slide 21, movable on the base ate 20 of the machine, so that the disk may be moved 1on itudinally of the machine.

The slide is loc ed in adjusted position by a manually controlled catch 24, which is acted upon by a spring and is swingable on a pin 25 fixed to the plate 22, the said catch engaging notches provided in the base late 20. Each of the-said disks has nine radia ins 26, which are movable in guides, provided in the disk, and are acted upon outwards by springs 27. The card 2 is moved by the rolls 16,17 through a guide provided in the calculating machine and past the disks 19, the

latter being so positioned that the pins 26' l spring 23 is able to yield laterally from the disk and has a curved slot 31, which is open at its lower end and the centre of which is I located onthe axis of the shaft 18. The top end of the spring 23 is bent outward into a curve, as shown in Fig. 4, and has a cam surface 32, from which a curve shaped edge 33 extends downward, the centre of which is located on the axis of the shaft 18. The pins 26 have lateral projections 34 extending through radial slots 36 in the disk 19 and limiting the outward movement of the pins, while the pins 26 are in their outer posltion the projections 34 are located on an arc, the radius of which is equal to the radius of the slot 31. lVli-ile, the disk 19 is rotated, the projections 34 strike the top end of the spring 23. 37 is a lateral pin provided on the disk for the pur ose stated below.

The cran 6, feedrolls 9, 10 and 16, 17 and the shaft 18 together with thedisks 19 are rotated synchronously, for instance by a motor and by means of suitable'gearing, not shown, so that the card is moved at the same velocity by the'plate 5 and by the feed rollsand the velocity of the card and the peripherical velocity of the disks 19 and the velocity of the teeth are equal. Besides, the parts are so adjusted, that, when a card is pushed down into the calculating machine, the first pin of the disk'19, rotating in the direction of the distance from the same. During the rotary motion of the disk the pin 37 first strikes the spring 23 and bows the same in a lateral sense. The distance between the pin 37 and the projection 34 of the first pin 26 with relation to the rotary direction of the disk is so adapted,that the projection 2340f the first pin has passed under the spring 23, before the pin 37 has arrived at the slot 31, so that the projection of the first pin' keeps the spring 23 in the said lateral position and for such a period, that the projection'of the next pin has time to arrive at a position under the spring, provided that the said pin has not been forced backwards by the unslotted part of the card, following the slot a. .In this manner the projections of the pins are successively brought into aposition under the spring 23. As the pro ection 34 ofthe pins respectively arrives at the slot 31, the spring 23 is moved somewhat inward toward the disk 19, so that the pro- 'ection enters the slot 31 and is prevented y the same from being pushed backward by the pressure executed by the toothed wheel 28 during the passage of the pin past thesaid wheel. Consequently, the toothed wheel 28 is rotated for as, many teeth as there are pins entering the slot a. As the unslotted part of the card, sequent to the slot a, arrives at the disk 19, the pin, which first strikes the said part, isforced inward, so that the projection 34 of the said pin does not occupy a position under the spring23. Consequently, as the projection of the -next preceding pin enters the slot 31, the spring 23 will bear against the disk 19, which results in theprojections 34 of all succeeding pins sliding along the cam surface 32, being forced inward and then following the edge 33. For that reason no one of the succeeding pins can enter the supplementary slot b but are held in retracted position by the spring 23 while passing the toothed wheel 28. Consequently,the disk 19 rotates the toothed wheel 28 for a number of teeth corresponding to the length of the slot or. Thusyif the slot a-represents the numeral 6, six pins 26 will enter the said slot and rotate the toothed wheel 28 through a distance corresponding to six teeth. The toothed wheel '28 meshes with aregistering wheel 38, which together with an indicating disk 39 fixed to the wheel is freely mounted on-a shaft 40 andhe-ld in adjusted position by a pawl 42, acted upon bya spring 41 and engaging thesaid registering wheel. The numerals on the disk'39 are visible through an opening 43 provided in .the casing The said registering wheel 38 is located be tweentwo plates 45 extending upward from a slide 46, movable on the base plate 20 of the machine. The said slide may be locked in adjusted position by a spring actuated, manually controlled pawl 47, which is pivoted to the slide and engages notches provided in the base plate 20.- The intermediate wheel 28 is rotatable on a pin 48 in the slide. Laterally of the wheel 28 a tentransmitting arm 50 is provided, which is swingably'mounted on a pin 49 in' the slide and is of the construction used in Odhners calculating machines, U. S. Letters Patent- No. 209,416. As the said arm is forced toward the right by a pin 51 provided on the indicating disk, 39, it shifts laterally, in known manner, a spring actuated ten-pin 52 for carrying tens, hundreds and so on, which swings on the disk 19, so that the said pin 52 actuates the intermediate wheel ene space corresponding to the indicating disk of the next higher value. The ten-transmitting arm is locked in operative position by a catch of the same construction as for instance the catch provided in Odhners calculating machines above mentioned. The ten-pin is so located on the disk 19, that it is moved into operative position by the arm 50, when the card has passed through the calculating machine and before the next card arrives at the disk 19. Arm 50 is re turned into its inoperative position by a cam 9% provided on the disk 1. The indicating disks 39 may be returned to the zeroposition in the same manner as in Qdhners calculating machines before mentioned, for which reason the means used for that purpose are not described. As seen from the above, the calculating machine is arranged in substantially the same manner as Odhners calculating machines with the exception ofthe arrangement of the pins 26 and the parts actuating the same.

As stated above, each of the disks 19 is movable laterally by means of its slide 21. In the same manner each set comprising an intermediate wheel 28, a registering wheel 39, with pawl 42, and ten-transmitting arm 50 are mounted in their slides 46. Consequently, the disks 19 and each set or group of the calculating device may be located in that place in the machine, at which the slots of the cards pass, the numeral data of which is to be summed up. Two or more disks and corresponding sets of the calculating devices may be located at the side of one another respectively, so that tens, hundreds, etc. are transmitted.

if the numeral data, represented by the slots of a single section of the cards, is to be summed up, this is effected by means of a summing up device of simple construction, which, provided on a slide 53, may be located above the registering wheel 38 from which the summing up operation should be continued. @n pins 54c, 55, 56 provided in the said slide, indicating disks 5?, 58, 59, are mounted. As the re istering wheel 38 has been rotated through a distance of ten teeth the ten is transmitted by a pin 60 and an intermediate wheel 60 to a toothed wheel 61 connected with the ten-disk'57, a pin 62 provided on the disk 57 transmits hundreds to the hundreddisk 58 and so on. lhe numerals on the disks 5?, 58, 59, which are held in adjusted position by suitable catching devices, are visible through openings 63 provided in a casing 64 enclosing the calculating dev' :e. The machine has a plurality of simple summing up devices of the type last described and adapted to be located above the registering wheels (38) respectively. As the simple summing up device is to be used, the ten-transmitting arm 50 must be brought out or" op-ration, in order that an adjacent calculating device may not be disturbed by the ten-pin of the disk 19. For that purpose the head 50* of the arm 50 is pivoted to the arm and is normally held by a spring 65 against an abutment 65 provided on the arm, see Figures 8 to 10. In order to swing the said head 5O into a position in which it is not actuated by the pin 51 and consequently is not brought into the position in which it shifts the carrying pin 52 for tens and other values, a pin 66 is provided on the slide 53, having a cam piece 66 which, as the slide is located above the registering wheel 38 forces the left end of the head 50 downward, as shown in Figures 9 and 10, and consequently raises the right end of the same, so that the pin 51 can freely pass the head 5O and th latter does not make contact with the tens pin. When the numeral data of a plurality of associated columns are to be summed up a vertical summing up device of the type just described enerally must be located above the indicating disk, which corresponds to the leftmost one of the columns in question. i

As the card'leares the calculatin machine, it is seized by two rolls 67, 68, w ich move the card past an angular lever arm 71, which is pivoted at 70 and actuated by a spring 69. The said lever arm carries a pawl 72 engaging a ratchet wheel 73, which together with an indicating disk 74 is rotatably mounted on a pin 75. The said indicating disk 74 belongs to a calculating device, which indicates the number of cards which have passed through the machine and may be arranged like an ordinary stroke-counter.

In the calculating machine shown in Fig. 6 a suitable number of shafts is provided, one of which is shown and designated by 76.

The said shafts are rotated continuously by means of any suitable driving device and there is provided for each shaft a calculating device of the construction shown in Fig. 6. The rotary motion of the shaft 7 6 may be transmuted to a shaft 77 by means of a claw-coupling 78, 79, which is brought into and outof operation in the manner stated below. The card 80, Fig. 7 is moved through the machine and past a lever 88, 84 by two pairs of rolls 81, 82. Qne arm 83 of the lever is provided with a roller 85, which by a spring 86* is forced toward the'card. The other arm of the said lever actuates the slidable part 78 of the coupling. While the card 80 is moved in the direction indicated by the arrow, the roller is forced downward into the slot (.1 of the card and in this manner the coupling is caused to operate. Consequently, the period, during which the coupling is operative, corresponds to the length of the slot at, which on the other hand corresponds to a number from O to 9v inclusive. In the said manner the shaft 77 is ro-- tated by the coupling 8, 7 9 through an anregistering wheel 87 with,,indicating disk 88. Consequently, if the slot a represents numeral 8, th indicating disk 88 will bemoved eight steps by the described device. The transmitting of tens, hundreds etc. is

effected by means of a ten-pin 89 etc. whichmay be of ordinary construction and carried for instance by a disk 90, which by suitable means is driven synchronously to the card and in such manner, that thepin 89 passes the intermediate wheel 86 during a period in which the slot a is away from the roller 85. The ten-pin etcJis brought into operative position in the ordinary manner by a ten-transmittingarm 91 an a pin 92provided on the indicating disk 88. In order.

that the coupling 78', 79 may not be brought into operative position, while the supplementary slot 6 passes the roller or during the period between two cards, the machine is provided with a cam disk 93, which is so arranged and is rotated at such a velocity, that it keeps the coupling in inoperative position,

during the said periods.

Also in the calculating machine shown in Fig. 6 the shaft 76 and the calculating device belonging to the same may be provided in a laterally adjustable slide, so that the calculatin devices may be placed at the slots respectively and be combined to necessary sets. Also the vertical calculating devices shown in Figs. 3 and 4 may be used in thecalculating machine shown in Fig. 6.

The invention may be carried out in many other manners Without exceeding the limits of the invention. If cards of the type shown in Fig. 7 are used, the calculating machine may be simplified in such manner, that the spring 23 is dispensed with. This is due to the fact that in the said card the slots, the data of which are to be calculated, are situated in a part of the card which is fully separated from their supplemental slots. The machine is then so arranged, that the pins 26 arrive just at the slots a during the passage of the cards through the machine.
